Abstract
Abstract An elongated substantially cylindrical toy simulating the head end portion of a snake including a throat portion, flanges, and head having a base member opposite the head is adapted to be balanced in an upright position in the palm of a player''s hand. An electrical circuit, including lamps selectively located in the toy and a time delay circuit for each lamp, a source of electrical energy and manually operated switches adjacent the base, is contained by the toy which selectively energizes the lamps in a predetermined sequence while the toy remains balanced. A plurality of mercury switches are located in the body and are connected in series between the source of electrical energy and lamps. If the toy is caused to tilt beyond a certain point the mercury switches open and deactivate the time delay circuits and lamps.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
97 words
A balancing device, comprising: an elongated hollow body; and, an electrical circuit contained by said body, said circuit comprising a plurality of lamps, a source of electrical energy, in series circuit with each of said lamps time delay means in electrical circuit with said source of electrical energy and said lamps for causing said lamps to become illuminated sequentially; and inclination sensitive means in series circuit between said lamps and said source of electrical energy for breaking the circuit between said lamps and said source of electrical energy when said body is inclined beyond a certain angle.
Claim 2
Dependent Claim
97 words
A balancing device, comprising: an elongated hollow body; and, an electrical circuit contained by said body, said circuit comprising a plurality of lamps, a source of electrical energy, in series circuit with each of said lamps time delay means in electrical circuit with said source of electrical energy and said lamps for causing said lamps to become illuminated sequentially; and inclination sensitive means in series circuit between said lamps and said source of electrical energy for breaking the circuit between said lamps and said source of electrical energy when said body is inclined beyond a certain angle.
Claim 3
Dependent Claim
58 words
The toy according to claim 1 wherein said inclination sensitive means comprises a plurality of mercury switches, said mercury switches being normally closed when said body is disposed vertically and at least one of said mercury switches being opened in response to said body being inclined beyond a predetermined angle with respect to the surface of the earth.
Claim 4
Dependent Claim
26 words
The toy according to claim 2 in which said plurality of lamps are disposed in spaced-apart relation throughout at least one end portion of said body.
Claim 5
Dependent Claim
34 words
The toy according to claim 3 in which said time delay means includes: a plurality of time delay sections, each time delay section being connected with at least one of said plurality of lamps.
Claim 6
Dependent Claim
108 words
The toy according to claim 4 in which each said time delay section includes: a transistor; a silicon controlled rectifier; a unijunction transistor; and, a potentiometer the base of said transistor being connected to the anode of said silicon controlled rectifier, said potentiometer being connected at one end to the collector of said transistor and at the other end to the emitter of said unijunction transistor, one base of said unijunction transistor being connected to the control gate of said silicon controlled rectifier, and the anode of said silicon controlled rectifier being connected in series with the source of electrical energy through at least one of said lamps.
Claim 7
Dependent Claim
30 words
The toy according to claim 5 in which said body is characterized by an open base end and a closed head end portion; and, a cap closing said base end.
Claim 8
Dependent Claim
28 words
The toy according to claim 6 in which said body is formed of translucent material and said head end portion simulates the head end portion of a snake.
